“…Improved production processes (e.g., drying seaweed) that reverse this situation are required [86]. Moreover, Slegers and colleagues [87] conducted a LCA research on the current state-of-the art cultivation of seaweed (S. latissima) (for use in vegetarian burgers) "in the Dutch Exclusive Economic Zone of the North Sea." They conclude that the current cultivation impact which varies between 10 and 52 kg CO 2 eq/kg wet weight seaweed, being the (time and) vessels used for the transportation of the cultivation modules and for harvesting the most important (70-75% impact) GWP of the production system [87].…”

At a 20% DM content, this would mean a footprint of 1 kg CO 2 eq per kg DM; this is substantially lower than current numbers given for soya bean meal at ~5 kg CO 2 eq per kg DM, but slightly higher than maize (~0.7 kg CO 2 eq per kg DM) and wheat (0.5 kg CO 2 eq per kg DM) according to the calculation method in van Dijk et al [88].…”

“…Avoid the Production of Unnecessary Products and Use/Recycle Biomass Effectively (Food vs. Feed) Seaweeds might have a high nutritional value [87,89]. Moreover, seaweed contains elements such as vitamin B12 and carotenes that generally are delivered by animal-based products [87]. However, seaweed can have a high salt content, which can limit application in food [87] and feed [75].…”

A Circularity Evaluation of New Feed Categories in The Netherlands—Squaring the Circle: A Review

2022

View full text Add to dashboard Cite

The concept of circularity is currently proposed to address key sustainability issues affecting and affected by livestock production. Through a desk study, this paper evaluates some feed sources that are being developed in The Netherlands as an alternative to current feeds, namely food waste; seaweed; and localized production and alternative plant-based feed sources. These feed categories are evaluated according to four circularity criteria. The first two criteria concern standard circularity principles aimed at both stopping and preventing environmental damage as well as a focus on natural resources use efficiency: (1) Safeguard the health of ecosystems and (2) avoid the production of unnecessary products and use/recycle biomass effectively, as well as evaluating possible food–feed competition. In addition, two ‘people’ and ‘animal’ centred principles have been integrated: (3) fairness and accessibility and (4) animal health and wellbeing. The article concludes that people and animal centred principles are key to thinking of, developing, implementing, and evaluating circularity initiatives. Moreover, the article suggests that categories such as the local production of soya (approx. 132 ha) or seaweed (approx. 10–15 ha) are as yet irrelevant regarding production volumes within the Dutch context. However, some feed sources such as seaweed, insects, livestock leftovers produced at farms and abattoirs, and food waste might strengthen the transition towards more circular and sustainable practices.

Seaweed as climate mitigation solution: Categorizing and reflecting on four climate mitigation pathways

Global concerns about climate change were once again expressed at the COP27 in Sharm El‐Sheikh. Seaweed is frequently presented as a solution for climate mitigation. For a proper appraisal of its contribution to mitigating climate change, it is necessary to distinguish between, and critically scrutinize, the various pathways seaweed‐based climate mitigations can take. This article identifies four different climate mitigation pathways and critically reflects on each. First, carbon sequestration, occurring when grown seaweed is left in the seas or, second, purposefully sunk. Third, carbon emission reduction, resulting when seaweed‐based products replace products with a higher carbon footprint, either fossil based products or other organic material. Fourth, carbon emission avoidance, taking place when seaweed products are used to avoid greenhouse gas emissions in other production processes. Each of these pathways requires specific methods to quantify their magnitude and comes with critical questions to ask. The sequestration pathway requires monitoring of net carbon production and the amount of carbon that is eventually exported to the deep sea. Pathways 3 and 4 require Life Cycle Assessment and/or Carbon Footprint with system boundaries set to include the production system itself and installation thereof. We propose an unequivocal categorization in a belief that confusion on the benefits of seaweed will eventually impede development of seaweed‐based solutions.This article is categorized under: The Carbon Economy and Climate Mitigation > Benefits of Mitigation

The sugar kelp Saccharina latissima has received intense scientific attention over the last decades. In recent years, interest in cultivation of the species has strongly increased in the North Atlantic Ocean and the Eastern Pacific Ocean, driven by the great potential of S. latissima to be utilised for various industrial applications, including food, feed, and biomaterials. Accordingly, current research has focused on improving farming methods and technology, environmental impacts, and site selection. In addition, many studies have investigated the varying chemical composition of S. latissima, extraction of commercially interesting components, and the use of the biomass and its derived components in various applications. This review provides a comprehensive overview of farming and applications of S. latissima from the last 15 years. Additional insights on other research topics, such as ecology, physiology, biochemical and molecular biology of S. latissima, are given in the first review, “The sugar kelp Saccharina latissima I: recent advances in a changing climate” (Diehl et al. 2023).
